The invention relates to a document analysis method to detect BW/color areas comprising the following steps: getting an input image data to be split in elementary information; analysing the input data to get the colorfulness of each elementary information; creating a first and a second output layers corresponding to the BW and color elementary information respectively; applying a first set of atomic operations to the BW layer and a second different set of atomic operations to the color layer; and combining the BW and color layers in order to obtain a desired format for the output data. The invention also relates to a scanning device to acquire documents including an input that receives an input image data, and is connected to a layer creator component, which in turn outputs a first and a second layer, such layers having different data compression rate. Finally, the invention relates to a method for acquiring a document based on the analysis of the content of the document itself.

Document analysis method to detect BW/color areas and corresponding scanning device

The invention relates to an image data processing method receiving an input image data split in elementary units of information and providing an output image data with a particular image format depending on the requirements of a final device that receives such output image data by means of the following steps: identification of the final device that receives the output data; getting an input image data; from a repository of basic imaging operation, selecting a plurality of operations to be performed on the input image data; creating a sequence of operations that links and ordinate the plurality of operations; applying the sequence to the input image data to create a plurality of layers of organized data of said input image data; assembling said plurality of layers into at least an output layer which best fit the requirements of the identified final device; and sending the assembled output layer to the identified final device. The invention also relates to a configurable image processing device to read and output an image data in accord with a particular output format depending on a final device that receives the output image data.
